Dual-liquid pump dual-circulation integrated liquid-cooling device

A dual-liquid pump dual-circulation integrated liquid-cooling device, comprising a cooling radiator, two liquid pumps and a cold plate, wherein said cooling radiator comprises a first liquid box, a second liquid box, and a radiator tube set, said first liquid box being internally divided into two first chambers by a first partition, each said first chamber being provided with a second partition to separate the respective said first chamber into a liquid inlet chamber and a liquid outlet chamber, each said first chamber being internally provided with a liquid pump seat, each said liquid pump seat comprises a liquid pump chamber, a liquid inlet hole connected to said liquid pump chamber and said liquid inlet chamber, and a liquid outlet hole connected to said liquid pump chamber and said liquid outlet chamber, said second liquid box being internally divided into two second chambers by a third partition, each said second chamber being internally divided into a hot liquid chamber and a cold liquid chamber by a fourth partition, said hot liquid chamber being provided with at least one first hot liquid outlet connected to said cold plate, said cold liquid chamber being provided with a first cold liquid inlet connected to said cold plate, said radiator tube set comprises a plurality of parallel first radiator tubes, second radiator tubes, and heat dissipation fins, said first radiator tubes having respective one ends thereof connected to said liquid inlet chambers of said two first chambers and respective opposite ends thereof connected to said hot liquid chambers of said two second chambers, said second radiator tubes having respective one ends thereof connected to said liquid outlet chambers of said two first chambers and respective opposite ends thereof connected to said cold liquid chambers of said two second chambers;

• wherein said two liquid pumps are installed in said liquid pump chambers of said two first chambers respectively, said two liquid pumps respectively driving a hot liquid in said two hot liquid chambers of said second liquid box to flow through said first radiator tubes to said two liquid inlet chambers of said first liquid box, and then flow from said liquid inlet chambers into said liquid pump chambers respectively, and then flow to said two liquid outlet chambers of said first liquid box, and then flow through said second radiator tubes to said two cold liquid chambers of said second liquid box, allowing the hot liquid to dissipate heat through said radiator tube set and become a cold liquid;
• and
• wherein said cold plate is combined with a bottom surface of said second liquid box, said cold plate comprising a cold plate body and a heat dissipation base, said cold plate body comprising a top surface and an opposing bottom surface, the top surface of said cold plate body being combined with the bottom surface of said second liquid box, the bottom surface of said cold plate body being provided with an upwardly concave liquid chamber;
• said cold plate comprises two second cold liquid inlets connected to said two first cold liquid inlets, and two second hot liquid outlets connected to said two first hot liquid outlets, said heat dissipation base comprising a bottom plate and a plurality of micro water channels formed on a top surface of said bottom plate, said bottom plate being combined with the bottom surface of said cold plate body to seal said liquid chamber so that said micro water channels are located in said liquid chamber.
